実験手順

To a suspension of 210 mg (1 mmol) of 7-amino-6-(2,6-dichlorophenyl)-2-[3-(diethylamino) propylamino]-pyrido[2,3-d]pyrimidine from Example 20 in 0.8 mL of DMF was added 0.8 mL of DMF dimethyl acetal. The mixture was stirred at room temperature for 5.5 hours, then concentrated in vacuo. The residual oil was distributed between dichloromethane and water. The organic phase was dried over magnesium sulfate, then concentrated to a glass that was crystallized from acetonitrile to give 160 mg (68%) of N'-[6-(2,6-dichlorophenyl)-2-{3-(diethylamino) propylamino}-pyrido[2,3-d]pyrimidin-7-yl]-N, N-dimethylformamidine, mp 100°-104° C.
